 ### WebSockets binary data
 
-Websockify supports all versions of the WebSockets protocol (Hixie and
-HyBi). The older Hixie versions of the protocol only support UTF-8
-text payloads. In order to transport binary data over UTF-8 an
-encoding must used to encapsulate the data within UTF-8.
-
-With Hixie clients, Websockify uses base64 to encode all traffic to
-and from the client. This does not affect the data between websockify
-and the server.
